Memcached源码安装配置

Memcached源码安装配置

官方网站:

http://memcached.org/

http://www.monkey.org/~provos/libevent/

Free & open source, high-performance, distributed memory object caching system

环境:

CentOS 7.1/6.5

memcached-1.4.25

一.安装编译依赖库

yum -y install gcc gcc-c++ unzip gzip bzip2 libevent-devel cyrus-sasl-devel systemtap-sdt-devel

二.编译安装

wget http://www.memcached.org/files/memcached-1.4.25.tar.gz

tar -xvf memcached-1.4.25.tar.gz -C /usr/local/src

cd /usr/local/src/memcached-1.4.25

./configure --prefix=/opt/memcached

--enable-sasl

--enable-sasl-pwdb

--enable-dtrace

--enable-64bit

make -j4 && make -j4 install

cp -a /opt/memcached/share/man/* /usr/share/man

cp -a /usr/local/src/memcached-1.4.25/scripts /opt/memcached/

三.init sysv脚本

useradd -r -s /sbin/nologin memcached

mkdir -p /var/run/memcached/

cp -f /usr/local/src/memcached-1.4.25/scripts/memcached.sysv /etc/init.d/memcached

sed -i 's#daemon memcached#daemon /opt/memcached/bin/memcached#' /etc/init.d/memcached

sed -i "/^USER=/c USER=memcached" /etc/init.d/memcached

sed -i "/^CACHESIZE=/c CACHESIZE=2048" /etc/init.d/memcached

chmod +x /etc/init.d/memcached

chkconfig memcached on

四.配置并启动

init脚本启动

service memcached start

命令行启动

/opt/memcached/bin/memcached -d -u memcached -m 2048 -t 4 -p 11211 -P /tmp/memcached.pid

命令行停止

kill -9 $(cat /tmp/memcached.pid)或killall memcached

提示:命令行更为灵活，memcached -h可以查看所有可定制选项参数

测试

php扩展(memcached & memcache)

http://libmemcached.org/libMemcached.html

http://php.net/manual/zh/book.memcached.php

http://pecl.php.net/package/memcached

注意:php的memcached扩展，功能和特性比memcache扩展都要优秀

1.安装libmemcached

wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz

tar -xvf libmemcached-1.0.18.tar.gz -C /usr/local/src/

cd /usr/local/src/libmemcached-1.0.18

./configure && make && make install

2.安装php memcached扩展库

wget http://pecl.php.net/get/memcached-2.2.0.tgz

tar -xvf memcached-2.2.0.tgz -C /usr/local/src/

cd /usr/local/src/memcached-2.2.0

phpize

./configure --enable-memcached-json && make -j4 && make -j4 install

3.php.ini加载memcached.so

echo extension=memcached.so >>/usr/local/php/etc/php.ini

service php-fpm restart

memcached

memcached support	enabled
Version	2.2.0
libmemcached version	1.0.18
SASL support	yes
Session support	yes
igbinary support	no
json support	yes
msgpack support	no

但有些php GUI是基于php memcache的扩展库，所以这里也一并安装

http://php.net/manual/zh/memcache.installation.php

http://pecl.php.net/package/memcache

wget http://pecl.php.net/get/memcache-2.2.7.tgz

tar -xvf memcache-2.2.7.tgz /usr/local/src/

cd /usr/local/src/memcache-2.2.7

phpize

./configure && make -j4 && make -j4 install

echo extension=memcache.so >>/usr/local/php/etc/php.ini

 

 

service php-fpm restart

root@jlive:memcache-2.2.7#ls /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

php memcache GUI工具--MemAdmin

基于 PHP5 & JQuery 的 Memcached 管理监控工具，界面非常清爽

wget http://www.junopen.com/memadmin/memadmin-1.0.12.tar.gz

tar -xvf memadmin-1.0.12.tar.gz -C /usr/local/nginx/html

默认用户名和密码为admin/admin, memadmin/config.php可以修改
